For more information about transactions, see ...The DML approach, when combined with non-linear first stage models, like Random Forests or Gradient Boosted Forests, can capture such non-linearities and provide unbiased estimates of the effect of \(T\) on \(Y\). Moreover, it does so in a manner that is robust to the estimation mistakes that these ML algorithms might be making.

One of the important differences between DDL and DML is that Data Definition Language (DDL) defines the schema of the Database whereas the Data Manipulation Language (DML) is used to modify the schema of the Database.
